FIG. 1.

Normalized absorption spectra of the CoGa:ZnO thin films on (a) Co and (c) Ga -edges, and the radial distribution functions of (b) Co and (d) Ga from Fourier transform magnitude of EXAFS of Co and Ga -edges, respectively.

FIG. 3.

(a) The ratio of carrier density to the number of Co ions , saturation moment and anomalous Hall conductivity as a function of Ga concentration at 300 K. The inset shows the anomalous Hall resistivity and perpendicular magnetization for a typical sample at 300 K. (b) The saturation moment at 300 K as a function of ; the inset shows the loops of the CoGa:ZnO thin films with 2% Ga doping.
